It's just ads. If we're talking about some ad for a coffee maker, whatever.
Now their whole selling data to unscrupulous folks, taking money from parents via their kids, selling fake news that makes people hate other people (now that gets into the ad space...) ....
That's where I'd want to nope out.
I remember working as a junior developer on a desktop app that had so many fatal bugs that it crashed very often. Instead of being given the time needed to fix the crashes, I was told to build this watchdog ‘launcher’ EXE that would simply re-run the application every time it crashed, restoring its state, in the hopes of fooling the user into believing it doesn’t crash so much.
Was it technically interesting for a freshly minted engineer? Yea! Was it soul crushing to be working on an obviously half-assed attempt to mollify angry users instead of making them happy? Yes.
I was also asked to write code that cheated benchmarks. Definitely had a “what-am-I-doing-with-my-life” moment.
